Duh, yes, I typed this from my code instead of cutting and pasting.
rs = cmd.Execute()[0]
is what I meant, which does the same as what you have.

I'm not sure why you'd use GetRows.
while not rs.EOF:
print rs.Fields("FieldName1")
rs.MoveNext()
I often write a small wrapper around the recordset which turns it into a
generator, because inevitably, on the first round, I forget the MoveNext
and get an infinite loop:
def Recordset(cmd, sql):
cmd.CommandText = sql
rs = cmd.Execute()[0]
while not rs.EOF:
yield rs
rs.MoveNext()
for row in Recordset( cmd, "SELECT FieldName1 FROM MyTable" ):
print rs.Fields("FieldName1")
